The Hugong InverDelta400 is the most powerful model in Hugong’s electrode welder lineup. This professional-grade machine is built for heavy-duty work, extended use, and maximum performance.
Equipped with advanced IGBT inverter technology, the InverDelta400 ensures a stable arc and excellent energy efficiency. Adjustable functions such as hot-start, anti-stick, and ARC force provide full control over the arc and make welding more comfortable, even with challenging electrodes or welding positions. The machine supports electrodes from 1.6 to 5.0 mm, including rutile (E6013), basic (E7018), and cellulosic (E6010) types.
A digital display gives real-time insight into current and voltage. The built-in fan and safety features for overload and overvoltage protection ensure safe and stable performance, even during demanding jobs.
Key features:
- Twistlock 500A electrode holder
Equipped with a 500A twistlock holder and a 5-meter heavy-duty 35 mm² cable for maximum current transfer, minimal voltage drop, and high reliability.
- Stepless current adjustment
Smooth and precise control via a large rotary knob ensures optimal settings for material type, electrode size, and desired weld penetration.
- High load capacity and welding power
With a peak output of 400 amps and a high duty cycle, this machine is built for demanding and continuous welding without performance loss.
- Shock-resistant ABS housing
The durable ABS enclosure provides excellent protection against impact, dust, and light moisture (IP21S), making it suitable for tough work environments.
- 5-year warranty
Upon registration, you receive a five-year manufacturer’s warranty—proof of Hugong’s durable construction and long-term reliability.
